The present invention relates to a variable pitch feeder system of a press. In particular, in a feeder system for transferring a workpiece on a press, an apparatus for automatically controlling two pitch lengths of a workpiece during press processing, There is no need to stop the press in order to maximize the convenience and productivity of the operator relates to an apparatus.

In general, a press refers to a machine for bending, shearing, section shrinkage, or the like by applying plastic force to a material, and pressing is also called simply a press.

Representative examples of press work are plastic deformation, mainly by applying a compressive force to a metal plate to form various shapes, and are widely used from precision parts of watches and cameras to automobile bodies. Brass and aluminum plates as well as plastics and fibers are used.They can be processed without heating, and can be processed to precise dimensions and shapes in a short time, and are interchangeable and suitable for mass production. There is an advantage.

A feeder provided in such a press generally refers to a device for supplying a workpiece to a press by using the power transmitted from the press or for transferring a workpiece being processed on a press.

However, in the conventional feeder system provided in the conventional press, when adjusting the pitch, which is the moving distance of the workpiece according to one punching of the press, the pitch can be adjusted only when the press is stopped. Even if it is possible to process with a small number of processing by using the number of the workpiece on the workpiece does not match the unavoidable technical problem that must be processed by a large number of processing using a short pitch, the press work is very inefficient.

The present invention is to solve the above problems, by improving the feeder system for transferring the workpiece on the press to automatically control the feed pitch length of the workpiece during the press machining in two ways, thereby adjusting the pitch during press In order to provide a variable pitch feeder system of the press to maximize the convenience and productivity of the operator do not need to stop the press.

Perspective view.

The variable pitch feeder system of the press of the present invention, as shown in Figure 1 to 7, the drive rod 100 is repeatedly lifted in accordance with the operation of the press; A feeder mechanism 200 which is rotatably supported by the press body 600 to transfer the workpiece according to the rotation; A driven rod 300 connecting the lower end of the driving rod 100 and the feeder mechanism 200 to rotate the feeder mechanism 200; One side is rotatably supported at the hinge point 610 of the press body 600, the other side is the first link 410 connected to the lower end of the drive rod 100; A second link 420 of which one side is rotatably supported at the hinge point 610; A third link 430 of which an upper end is connected to an interruption of the driven rod 300, and a lower end thereof is connected to a free end of the second link 420; It can be selectively lifted by the hydraulic cylinder 510 fixed to the body 600, the upper end is composed of a pitch adjusting rod 500 connected to the interruption of the second link 420 as a basic technical feature do.

Hereinafter, referring to FIGS. 1 to 5, the operation of the present invention will be described.

The variable pitch feeder system of the press of the present invention configured as described above is related to a feeder system for transferring a workpiece on a press, as shown in FIG. 1, as shown in FIGS. 2 to 5. By additionally connecting the feed rod mechanism 200 which receives and lifts the driven rod 100 and the workpiece on the press with a plurality of links, the pitch, which is the transfer distance of the workpiece, is automatically selected without stopping the press during press working. It can be converted.

Here, the drive rod 100 is a bar-shaped component having a high rigidity that receives power from the press and moves up and down once when the punch is pressed once.

The lower end of the driving rod 100 is rotatably connected to the first link 410 and the driven rod 300, the connection center point is not supported in a separate structure.

And, the other side of the drawing that one side is the other side of the first link 410 connected to the drive rod 100 and the driven rod 300 is a plate-shaped upright fixed in front of the press as shown in Figs. It is rotatably supported at a pin-type hinge point 610 supported by the body 600 of the.

In addition, the left side of the drawing of the second link 420 is rotatably supported at the hinge point 610 of the body 600, and the right side of the second link 420 is a lower end of the third link 430. It is rotatably connected to, and the upper end of the third link 430 is rotatably connected to the interruption of the driven rod (300).

In addition, the pitch adjusting rod 500 is lifted by the hydraulic cylinder 510 fixed to the press body 600 to selectively maintain the raised or lowered state at the interruption of the second link 420. It is connected.

According to this configuration, except for the second link 420, which is constrained by the pitch adjusting rod 500 when the driving rod 100 is repeatedly lifted during operation of the press, the first link 410, The third link 430 and the driven rod 300 reciprocate in a predetermined trajectory, thereby transferring the workpiece to a predetermined pitch on the press through the feeder mechanism 200.

If the feed pitch for the workpiece is to be increased or decreased, the stopping restraint point for the second link 420 may be selectively lowered or raised by the hydraulic cylinder 510. By varying the position of the workpiece can be adjusted the pitch as shown in FIG.

Accordingly, in the present invention, when the pitch adjustment rod 500 is raised, the conveyance pitch for the workpiece is reduced. On the contrary, when the pitch adjustment rod 500 is lowered, the conveyance pitch for the workpiece is increased. will be.

That is, the stop support point of the second link 420 is changed according to the fixed height of the pitch adjusting rod 500 so that the restraint position is changed, so that the second link 420 is temporarily shown in FIGS. 4 and 5. In the fixed state, the rotation angle of the first link 410 and the feeder mechanism 200 is narrowed or extended on the same trajectory, while the third link 430 and the driven rod 300 have their trajectories themselves. It will change.

At this time, in the present invention, the feeder mechanism 200 has an arc-shaped guide rail 210 having a predetermined radius; A guide bracket 220 supporting the guide rail 210 so as to be movable in a radial direction, and the driven rod 300 being eccentrically connected to one side; A feeder shaft 230 fixed to the rear surface of the guide rail 210 so as to be rotatably supported by the press body 600; The feeder shaft 230 is fixed to the feeder shaft 230 and extends upwardly, and preferably includes a feeder rod 240 for repeatedly transferring the workpiece on the press according to the reciprocating motion.

According to this configuration, when the reciprocating actuation force is transmitted to the guide bracket 220 through the driven shaft 300, the guide rail 210 and the feeder shaft 230 reciprocally rotates within a predetermined angle range, so that the above The feeder rod 240 repeatedly conveys the workpiece while reciprocating on a predetermined trajectory with respect to the feeder shaft 230.

In particular, as the guide rail 210, the guide bracket 220, the feeder shaft 230, and the feeder rod 240 as described above, even if the pitch adjusting rod 500 is raised or lowered the driving rod ( 100 is lowered, that is, the feeder rod 240 transfers the workpiece so that the position advanced to the right in the drawing can always be the same position as shown in Fig. 4 (a) and 5 (a). will be.

That is, since the guide bracket 220 surrounds and supports the guide rails 210 having a predetermined radius, the radial flow of the guide rails 210 is not limited, so that only the pitch adjusting rod 500 is elevated. When the feeder rod 240 does not flow, the feeder rod 240 can perform the function of transporting the workpiece only when the drive rod 100 ascend.

In addition, the feeder rod 240 reciprocates by making a predetermined trajectory, thereby interlocking the workpiece on the press.

In addition, in the present invention, as shown in Figures 4 to 7, the upper and lower horizontal lifting panel 520, which is provided with a buffer member 521 on both sides is connected to the upper end of the pitch adjustment rod 500, A bracket 530 fixed to the upper side of the elevating panel 520 is rotatably connected to the middle of the second link 420 so that the hydraulic cylinder 510 has a lower stopper 541 having a predetermined height on the upper side thereof. ) Is supported by a fixing panel 540 provided to correspond to the buffer member 521; Between the fixing panel (540) and the body (600), a lower laminated block (550) for adjusting the lower limit height of the pitch adjusting rod (500) is inserted through thickness control; The vertical bar 560 provided with an upper stopper 561 at a lower end thereof to correspond to the buffer member 521 penetrates through the upper laminated block 570 that adjusts the upper limit height of the pitch adjusting rod 500 through thickness adjustment. Most preferably, it is fixed to the body 600.

Here, since the hydraulic cylinder 510, which is the medium for elevating the pitch adjusting rod 500, cannot finely adjust an upper limit height and a lower limit height, the upper limit height and the lower limit height of the pitch adjusting rod 500 are limited. It is good in the present invention to add the separate components as described above.

That is, as shown in FIGS. 2 to 7, the horizontal lifting panel 520 is fixed to the upper end of the pitch adjusting rod 500, and the cushioning members of synthetic resin series are respectively formed on upper and lower sides of both sides of the lifting panel 520. 521 is fixed with a fastening means such as a bolt, and the bracket 530 which is rotatably connected to the stop of the second link 420 is fixed to the central upper surface of the elevating panel 520.

Then, the hydraulic cylinder 510 for elevating the pitch adjustment rod 500 is fixed to the fixed panel 540 supported horizontally to the body 600.

Accordingly, as the pitch adjustment rod 500 is lifted, the lift panel 520 and the bracket 530 are lifted together to lift and stop the restraint point of the second link 420.

In addition, when the pitch adjustment rod 500 is lowered, as shown in FIGS. 4 and 6, the fixed panel 540 is provided on both sides of the fixing panel 540 to correspond to the buffer member 521 provided at the lower side of the elevating panel 520. A lower stopper 541 having a height is provided, and when the pitch adjusting rod 500 rises, the upper stopper 521 corresponds to the buffer member 521 provided above the lifting panel 520 as shown in FIGS. 5 and 7. A vertical bar 560 having a predetermined length provided with 561 is supported by the body 600.

In particular, by further inserting the lower laminated block 550 between the fixed panel 540 and the body 600, the lower limit height of the elevating panel 520 through the increase and decrease of the thickness to the lower laminated block 550 Can be arbitrarily adjusted.

Similarly, when the body 600 of the vertical bar 560 is fixed, the vertical bar 560 passes through the upper stacked block 570, thereby increasing and decreasing the thickness of the upper stacked block 570. The upper limit height of the elevating panel 520 may be arbitrarily adjusted.

As described above, the upper limit height and the lower limit height of the elevating panel 520 can be arbitrarily controlled, so that when the pitch adjusting rod 500 is elevated by the hydraulic cylinder 510, the upper limit height and the lower limit height are fine. Will be able to adjust.

That is, the upper limit height of the pitch adjustment rod 500 is determined according to the pitch B of the shorter length among the two pitches desired by the operator, and the lower limit height of the pitch adjustment rod 500 is the pitch of the longer length among the two pitches desired by the operator. It is determined according to A.

That is, it is possible to raise the pitch adjusting rod 500 to change to the pitch B without having to stop the press once the desired machining during the press working to pitch A in the state in which the pitch adjusting rod 500 is lowered. will be.

Referring to the drawings the operation example of the variable pitch feeder system of the press of the present invention configured as described above in detail as follows.

First, before the press working, the operator sets the pitch A and B of the desired two lengths, and then adjusts the upper and lower limit height of the pitch adjusting rod 500 to correspond to the pitch A and B.

First, the lower limit height of the pitch adjusting rod 500 is appropriately increased or decreased the thickness of the lower laminated block 550 in the state in which the hydraulic cylinder 510 is contracted, as shown in Figs. The bracket 530 fixed to the top of the rod 500 is to be connected to the interruption of the second link (420).

The upper limit height of the pitch adjusting rod 500 is a state in which the hydraulic cylinder 510 is extended to raise the pitch adjusting rod 500 as shown in FIGS. 5 and 7, and the pitch adjusting rod 500 is increased. After the buffer member 521 of the elevating panel 520 provided in contact with the upper stopper 561 of the vertical bar 560, the fixed height of the vertical bar 560 is supported by the press body 600 It is to be adjusted to the thickness of the upper laminated block 570 on the.

After setting the upper and lower limit height of the pitch adjustment rod 500 as described above by the operator to set the desired pitch A and B, the state that the pitch adjustment rod 500 is lowered through the hydraulic cylinder 510, that is, The press starts running at the lower limit.

While the driving rod 100 is repeatedly lifted as the press is operated, the pitch adjusting rod 500 is continuously held to restrain the second link 420 to restrain the driving rod 100. When the first link 410, the third link 430, and the driven rod 300 is moved on a constant trajectory as shown in Figure 4 (a) and (b) of the guide bracket 220 of the feeder mechanism 200 ) Rotates about the feeder shaft 230 in the forward and reverse directions.

At this time, since the guide rail 210 connected to the guide bracket 220 has its own curvature and the curvature of the force transmitted from the guide bracket 220 are different, the operating force transmitted from the guide bracket 220 is applied to the feeder shaft ( By transferring to the feeder rod 240 through 230, the feeder rod 240 is to repeatedly convey the workpiece on the press to a relatively long pitch A.

If the operator wants the workpiece on the press to be conveyed at a relatively short pitch B, if the hydraulic cylinder 510 is momentarily extended to raise the pitch adjusting rod 500 as shown in FIGS. 5 and 7, the pitch adjusting rod The cushioning member 521 of the elevating panel 520 provided in the 500 is in contact with the upper stopper 561 of the vertical bar 560 so that the pitch adjusting rod 500 is positioned at the upper limit height.

Accordingly, the bracket 530 provided on the pitch adjusting rod 500 raises the interruption of the second link 420, so that the restraint point of the second link 420 changes, so that the first link 410 ) And the feeder mechanism 200 has a narrow rotation angle on the same trajectory, while the trajectory itself of the third link 430 and the driven rod 300 is changed.

In addition, the guide bracket 220 of the feeder mechanism 200 connected to the driven rod 300 is rotated a predetermined angle in the radial direction of the guide rail 210 without rotating the guide rail 210, the pitch adjustment When the rod 500 is raised, the feeder shaft 230 and the feeder rod 240 are not rotated.

In this state, when the driving rod 100 is raised and lowered once, the pitch adjusting rod 500 restrains the second link 420 in an elevated state, so that when the driving rod 100 is raised and lowered, the first link ( 410, the third link 430, and the driven rod 300 move as shown in FIGS. 5A and 5B, with the guide bracket 220 of the feeder mechanism 200 centered on the feeder shaft 230. It will be rotated once in forward and reverse direction.

At this time, since the guide rail 210 connected to the guide bracket 220 has its own curvature and the curvature of the force transmitted from the guide bracket 220 are different from each other, the feed force transmitted from the guide bracket 220 is reduced. By transferring to feeder rod 240 via 230, the workpiece on the press is conveyed at a relatively short pitch B.

That is, during the press work, the workpiece can be transferred to the pitch B at a momentary time during the transfer of the workpiece to the pitch A.

For example, suppose a product is arranged in a length of 50 cm in the workpiece, the pitch for transferring the workpiece 20 cm is A, and the pitch for transferring 10 cm is B.

In this case, in the conventional press feeder system, since the pitch cannot be changed without stopping the press during the press working, the workpiece of 50 cm length can be processed only by processing five times at a pitch B of 10 cm.

On the other hand, in the case of the variable pitch feeder system of the press of the present invention, after processing twice with a pitch A of 20cm, the pitch adjusting rod 500 is instantaneously raised to process once with a pitch B of 10cm, 50cm length blood Being able to process the workpiece, there is an advantage that two times the number of perforations are reduced compared to the conventional.

Here, the stretching and contraction of the hydraulic cylinder 510 for elevating the pitch adjusting rod 500 is preferably set by the operator in advance in the control device that controls the control of the press, for example, the driving rod While the 100 ascends twice, the pitch adjusting rod 500 is kept in a lowered state, and thereafter, the pitch adjusting rod 500 is temporarily set to maintain the ascended state only during the remaining one ascending. You can let go.

Therefore, the variable pitch feeder system of the press of the present invention can switch between two pitches preset by the operator at a desired time point, thereby making it possible to press the product from the workpiece with a small number of processing times using a pitch as long as possible during press working. Since it can be obtained in large quantities, the number of times of press processing as well as the working time can be significantly reduced, not only can maximize the merchandise for the press, but also has an excellent advantage that can improve the convenience of the operator.

The above embodiment is an example for explaining the technical idea of the present invention in detail, and the scope of the present invention is not limited to the above drawings or embodiments.

The present invention as described above improves the feeder system for transferring the workpiece on the press, so that the feed pitch length of the workpiece can be automatically controlled in two ways during the press working, so that the press is stopped for the pitch adjustment during the press working. It is devised to maximize the convenience and productivity of workers.
